78.84. Casing standards.

 

(d) New or used plain end casing, except when being used as conductor pipe, that is welded together for use must meet the following requirements:

 

(1)   The casing must pass a pressure test by holding the anticipated maximum pressure to which the casing will be exposed for 30 minutes with not more than 10% decrease in pressure.  The operator shall notify the Department at least 24 hours before conducting the test.  The test results shall be entered on the drilling log.

 

 

Question:

 

Is pressure testing for welded surface casing necessary when a second string of casing is run?

 

 

Response: 

 

All welded casing strings, aside from the conductor pipe, must be pressure tested.  Well construction details have no bearing on this requirement.
